On the DM9000B, dm9000_msleep() is called during the dm9000_timeout() routine. Since dm9000_timeout() holds the main spinlock through the entire routine, mdelay() needs to be used rather than msleep(). Furthermore, the mutex_lock()/mutex_unlock() should be avoided so as to not sleep with spinlocks held. Signed-off-by: NAndrew Ruder <andrew.ruder@elecsyscorp.com> Signed-off-by: NDavid S.

On the DM9000A/DM9000B force the initial check of the link status. The DM9000A/B has a link status changed event and this interrupt bit isn't always set out of reset when a cable is plugged in. This results in the driver not seeing the cable attached link status until the cable is removed and plugged in again.

DM9000 uses level-triggered interrupts. Some systems (PXA270) only support edge-triggered interrupts on GPIOs. Some changes are necessary to ensure that interrupts are not triggered while the GPIO interrupt is masked or we will miss the interrupt forever. * Make some helper functions called dm9000_mask_interrupts() and dm9000_unmask_interrupts() for readability. * dm9000_init_dm9000(): ensure that this function always leaves interrupts masked regardless of the state when it entered the function. This is primarily to support the situation in dm9000_open where the logic used to go: dm9000_open() dm9000_init_dm9000() unmask interrupts request_irq() If an interrupt occurred between unmasking the interrupt and requesting the irq, it would be missed forever as the edge event would never be seen by the GPIO hardware in the PXA270. This allows us to change the logic to: dm9000_open() dm9000_init_dm9000() dm9000_mask_interrupts() request_irq() dm9000_unmask_interrupts() * dm9000_timeout(), dm9000_drv_resume(): Add the missing dm9000_unmask_interrupts() now required by the change above. * dm9000_shutdown(): Use mask helper function * dm9000_interrupt(): Use mask/unmask helper functions Signed-off-by: NAndrew Ruder <andrew.ruder@elecsyscorp.com> Signed-off-by: NDavid S.

* Change a hard-coded 0x3 to NCR_RST | NCR_MAC_LBK in dm9000_reset * Every single place where dm9000_init_dm9000 was ran, a dm9000_reset was called immediately before-hand. Bring dm9000_reset into dm9000_init_dm9000. * The following commit updated the dm9000_probe reset routine to use NCR_RST | NCR_MAC_LBK: 6741f40d DM9000B: driver initialization upgrade and a later commit added a bug-fix to always reset the chip twice: 09ee9f87 dm9000: Implement full reset of DM9000 network device Unfortunately, since the changes in 6741f40d were made by replacing the dm9000_probe dm9000_reset with the adjusted iow(), the changes in 09ee9f87 were not incorporated into the dm9000_probe reset. Furthermore, it bypassed the requisite reset-delay causing some boards to get at least one "read wrong id ..." dev_err message during dm9000_probe.

If an MPLS packet requires segmentation then use mpls_features to determine if the software implementation should be used. As no driver advertises MPLS GSO segmentation this will always be the case. I had not noticed that this was necessary before as software MPLS GSO segmentation was already being used in my test environment. I believe that the reason for that is the skbs in question always had fragments and the driver I used does not advertise NETIF_F_FRAGLIST (which seems to be the case for most drivers). Thus software segmentation was activated by skb_gso_ok(). This introduces the overhead of an extra call to skb_network_protocol() in the case where where CONFIG_NET_MPLS_GSO is set and skb->ip_summed == CHECKSUM_NONE.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-06-05 This series contains updates to i40e and i40evf. Jesse fixes an issue reported by Dave Jones where a couple of FD checks ended up using bitwise OR where it should have been bitwise AND. Neerav removes unused defines and macros for receive LRO. Fix the driver from allowing the user to set a larger MTU size that the hardware was being configured to support. Refactors send version which moves code in two places into a small helper function. Kamil modifies register diagnostics since register ranges can vary among the different NVMs to avoid false test results. So now we try to identify the full range and use it for a register test and if we fail to define the proper register range, we will only test the first register from that group. Then removes the check for large buffer since this was added in the case this structure changed in the future, since the AQ definition is now mature enough that this check is no longer necessary. Mitch fixes i40evf driver to allocate descriptors in groups of 32 since the hardware requires it. Also fixes a crash when the ring size changed because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers or leak leftover buffers. Fixed the driver to notify the VF for all types of resets so the VF can attempt a graceful reinit. Shannon refactors stats collection to create a unifying stats update routine to call the various stat collection routines. Removes rx_errors and rx_missed stats since they were removed from the chip design. Added missing VSI statistics that the hardware offers but are not apart of the standard netdev stats. v2: dropped patch "i40e: Allow disabling of DCB via debugfs" from Neerav based on feedback from David Miller. ==================== Signed-off-by: NDavid S.

i40evf_set_ringparam was broken in several ways. First, it only changed the size of the first ring, and second, changing the ring size would often result in a panic because it would change the count before deallocating resources, causing the driver to either free nonexistent buffers, or leak leftover buffers. Fix this by storing the descriptor count in the adapter structure, and updating the count for each ring each time we allocate them. This ensures that we always free the right size ring, and always end up with the requested count when the device is (re)opened.

Since v2.4 the capi driver used the following device nodes if "middleware" support was enabled: /dev/capi20 /dev/capi/0 /dev/capi/1 [...] /dev/capi20 is a character device node. /dev/capi/0 (and up) are tty device nodes (with a different major). This device node (naming) scheme is not documented anywhere, as far as I know. It was originally provided by the capifs pseudo filesystem (before udev became available). It is required for example by the pppd capiplugin. It was supported until a few years ago. But a number of developments broke it: - v2.6.6 (May 2004) renamed /dev/capi20 to /dev/capi and removed the "/" from the name of capi's tty driver. The explanation of the patch that did this included two examples of udev rules "to restore the old namespace"; - either udev 154 (May 2010) or udev 179 (January 2012) stopped allowing to rename device nodes, and thus the ability to have /dev/capi20 appear instead of /dev/capi and /dev/capi/0 (and up) instead of /dev/capi0 (and up); - v3.0 (July 2011) also removed capifs. That disabled another method to create the /dev/capi/0 (and up) device nodes. So now users need to manually tweak their setup (eg, create /dev/capi/ and fill that with symlinks) to get things working. This is all rather hacky and only discoverable by searching the web. Fix all this by renaming /dev/capi back to /dev/capi20, and by setting the name of the "capi_nc" tty driver to "capi!" so the tty device nodes appear as /dev/capi/0 (and up).

The Kconfig symbol ISDN_DRV_AVMB1_VERBOSE_REASON is only used for capi_info2str(). That function is only used in capidrv.c. So setting it without setting ISDN_CAPI_CAPIDRV is pointless. Make it depend on ISDN_CAPI_CAPIDRV, rename it to ISDN_CAPI_CAPIDRV_VERBOSE and put its entry after ISDN_CAPI_CAPIDRV's entry. Since this symbol seems to be primarily used for debugging, keep it off by default. By now the last users of capidrv hopefully know all they need to know about the reasons for disconnecting.

由 Tom Herbert 提交于
When creating a GSO packet segment we may need to set more than one checksum in the packet (for instance a TCP checksum and UDP checksum for VXLAN encapsulation). To be efficient, we want to do checksum calculation for any part of the packet at most once. This patch adds csum_start offset to skb_gso_cb. This tracks the starting offset for skb->csum which is initially set in skb_segment. When a protocol needs to compute a transport checksum it calls gso_make_checksum which computes the checksum value from the start of transport header to csum_start and then adds in skb->csum to get the full checksum. skb->csum and csum_start are then updated to reflect the checksum of the resultant packet starting from the transport header. This patch also adds a flag to skbuff, encap_hdr_csum, which is set in *gso_segment fucntions to indicate that a tunnel protocol needs checksum calculation Signed-off-by: NTom Herbert <therbert@google.com> Signed-off-by: NDavid S.
